US Sales Tax Filing for eCommerce Sellers


Are you an eCommerce seller with retail sales in the US?

Chances are you’re thinking about indirect taxes; am I on the hook for US sales taxes?; can I file automatically or do I need support on the ground?

The US sales tax regime is no small feat to try and get your head around, so we’ve outlined the basics below.



Let’s get this one out of the way first. There is no UK VAT on goods sold to B2B or B2C customers in the US.


US sales taxes

As a general rule, goods sold into a US state from outside are subject to a sales tax. Sales tax varies though from one state to the next. There is no single US sales tax rate.

Additional local government or city taxes in some states only add to the complexity!


When do I have to register?

Thresholds are set by sales value and / or by volume of transactions state by state. For example, $500k annually for California, but $100k or 200 transactions in Illinois. Such a transactions threshold may be significant to an eCommerce seller, even though the sales price may not be substantial. Some states have no sales tax at all.

You’ll find the full set of thresholds here on TaxJar.

A seller will need to register with the state tax authority if it meets the threshold in that location. There is, therefore, the potential for more than one state registration.

Monthly indirect tax filing is the default, but there may be wriggle room depending on your volume of activity.


Does it matter whether I am selling via an online marketplace or my own website?


If you are selling via an online marketplace facilitator then, as a general rule, you don’t need to do anything. The facilitator will calculate, collect and remit your sales taxes, even if you don’t have a state tax registration.

If you’re not selling via an online marketplace then you need to register. Note that Shopify, unlike, for example, Amazon, eBay and Etsy, is not considered a marketplace facilitator. The Shopify seller is responsible for registration and for remitting the sales tax.

If you hold inventory in an Amazon fulfilment centre then you almost certainly have “nexus” in that state.


OK, I need to register. How can I make the process as painless as possible for me?

You can appoint a US fiscal representative to manually file your indirect taxes. Be mindful though, filing all of those returns by state could become costly.

In an ideal world, your sales taxes are taken by direct debit. It all happens automatically.

TaxJar is, by its own admission, “focused on solving a problem no one wants to deal with: sales tax”. TaxJar makes sales tax filing easier for online sellers across the globe. AutoFile is TaxJar’s automated electronic filing service for state sales tax.


Amazing! How do I sign up?

You can enrol in AutoFile if your business has a US bank account, but to set one of those up, you need to incorporate over there.


An alternative solution...
